More rain and snow are on the way in your Monday forecast, and we'll continue to see the potential for more wet weather through early Wednesday. Most of the rain and snow will be falling in areas of the Northern Mountains early today, and then we'll start to see chances for rain and snow picking up from west to east through the rest of the day. Valley areas will start to see showers as early as mid day, with heavier showers likely this afternoon into the evening. foothill and Sierra locations will start to get a better chance for wet weather later this afternoon into this evening. A Winter Storm Warning is in effect now through midnight in northern Trinity County above 4500'. Siskiyou County will be under a Winter Storm Warning from 10am this morning through 10pm tonight down to as low as 3000', and the northern Sierra will be under a Winter Storm Warning from 7pm tonight through 6am Wednesday. A Winter Weather Advisory will also go into effect for portions of Lassen and Plumas Counties from 10pm tonight through 4am Wednsday. Snow levels will be down to as low as 3000' in Siskiyou County, down to around 4000' in Trinity County, and down to around 5500' in the northern Sierra today. We also have a Flood Watch in effect for portions of Trinity and Siskiyou Counties through 4am Tuesday due to heavy rainfall over abundant snow. Streams and creeks could overflow, and ponding water will be possible. Foothill areas are expecting to see rain exclusively from this wet system. Temperatures are starting out in the valley and foothills this morning, while mountain aresa are in the 20's to 30's this morning. Winds will be out of the south to around 20mph later today, and we could have gusts up to around 30mph. High temperatures will top out in the mid 50's to lower 60's in the valley, mid 40's to mid 50's in the foothills, and upper 30's to upper 40's in our mountain areas this afternoon.
The heaviest rain and snow is projected to fall tonight through Tuesday in the valley, foothills, Sierra, and Cascades. We'll also have the potential for thunderstorms in the valley on Tuesday afternoon. Snow levels will dip to as low as 3500' in the Sierra on Tuesday. Temperatures will be very similar on Tuesday to what we'll end up with on Monday. Lighter showers will linger from Tuesday night into early Wednesday, but we are expecting to dry out by late Wednesday afternoon. The low pressure that's bringing this active weather will be off to our east by Thursday, and high pressure will be building into our region. This will result in the return of sunny skies, dry weather, and a warming trend on the way. We'll be staying sunny and dry through this weekend. Temperatures will climb back into the low to mid 60's in the valley in your extended forecast, while foothill areas end up in the 50's to around 60 degrees, and mountain areas climb back into the 40's to 50's.
